Havrouns are uncommon and powerful norn shamans. Their duty is to tend to the needs of the Spirits of the Wild, in this world and the next. Havrouns are intimately connected with the Spirit that they serve, and there is only one havroun per Spirit of the Wild.
Havrouns are the only shamans powerful enough to spirit walk. This ability allows the havroun to cross over into the Mists without the need of a portal or a ritual, by leaving their bodies behind. They may also create portals that will allow them to cross over in body, as well as take allies with them.
Not all the Spirits have a havroun at any given time. No norn has been blessed as havroun for Ox, Eagle, Wolverine, or many others, in generations. Havrouns maintain a close connection with their Spirit, even more so than Speakers. Because of this connection, the last havroun of Owl was able to confirm her death.
When a havroun feels that they have grown old or weary, they usually begin to teach an apprentice that will take over their role as they prepare for their final crossing into the Mists.
